My invention relates to improvements in tellu'rians.

The object of my invention is to produce a telluriau which will be simple and inexpensiveof construction, be durable, and which will be adapted to illustrate the greatest possible number of phenomena for the simplicity of its design.

The same'letters and numbers refer to the lsame parts in differentfigures.

the construction and arrangement of con? nected and co-operating parts which are secured together and have no relative motion such parts are shown in Fig. with-common sectionin'g.

B is a base 'or support for theapparatus and has a nat top surface, on which illustrations and diagrams are shown.

C Dis a column supporting the apparatus, and its axis passes through the sun S. The sun is supported on the top` of the Wire 34, which is secured in the end F of the column C D. The earth is supported and carried by the lever L, which is pivoted on the end F of the column C D, and moves ina horizontal plane about the vertical axis U3 v3 in the direction of the arrows r r, Figs. 3 and 4, which thus carries the earth around the sun in adirection from west to east.

The device is constructed to operate automatically and regularly, so that it Will not require manipulation when used in lectures. A coiled spring 27, Figs. 2 and 3, is secured at one end to the top F of the -column C D,

the leverL and is capable of turning the lever L about the pivot F in the direction of the arrows r r. `Any suitable means may be `employed for regulating the speed of rotation of the lever L under the force of the spring 27, as a pawl-and-ratch'et device.

1 is a stationary spur-wheel on the column C, and 2 a pinion engaging the wheel 1 and supportedon and turning with the bearingpin Z, which is supported by a second lever N, pivoted tothe column D by a boss Y, and which turns with the lever L by suitable connections.

31 represents a balance-wheelv for controlling the speed of rotation about the column' C D caused by the spring 27. Any other suitable speed-regulator may be connected to ythe bearing-pin IZ for regulating the action i and the other end is secured by the pin 2S to 55 of the spring 27 and the speed of the lever L.

The earth E is supported and carried by the crank-arm Q, which is secured to the upper end of the shaft WV, that is held and turns in the boss O on the end of the lever L.v The axis of vrotation o a of the earth is inclined to the vertical line'o o through the shaft W, so y that the equatorialplane of rotation e e may be inclined twenty-three and one-half degrees to the plane of the earths orbit h h, as shown inFig. 2. The earth E is supported and turns on a sleeve V, shown made integral with or attached to the arm Q A collar connected to the earth E, turns upon and about the lower end of the sleeveV and has a bevelpinion 14, which engages the spur-wheel 1-3 on the shaft X, that is held and turns in the boss R on the end of the arm Q. The earth is rotated about its axis ct a When-the arm Q turns about the axis o v by the wheels 11 12 13. The spur-wheel 11 is connected to the boss O on the Vlever L and is stationary. When the arm Q turns about the axis no in the direction of the arrow r2, Fig. 3, the wheels l12 and 13 turn in the direction of the arrow r3 and thus cause the bevel-pinion 14.y and the earth E to rotate in the direction of the arrows r4, Fig. 3, or .from west to east. The arm Q is rotated by means of the bevelwheels 3 4 5 6 and the shafts 17 and W'. The shaft 17 is supported under the lever L by means of the lugs 29, and the shaft Wis supported in the boss O on the end of the lever L. The bevel 3 is stationary, so that when IOO bearing in thelug 30, cast to theunder side` per end V26 of the sleeve V ismade square,

it the bevel 4: is caused to rotate, whence the bevels 5 and G rotate and cause the arm Q to turn in the direction of the arrow r2, Fig. The apparatus so far described is designed to cause the earth to change its ecliptic inclination during the `annular rotation of the earth around the sun. lf the relative positions shown are those of the 1st of July, then on the ist of January the arm Q would project in the opposite direction relative to L, or toward -the sun, and the earths axis would then be inclined at the top away from the sun. When the bodies S and E come into the positions shown again, it will be the 1st of July again, and the earth will have made an annual revolution. Consequently the operating mechanism must be proportioned so that the proper relative velocities will be given to the earth and nioon in their motions about the sun.

means ,of the mechanism Q 7 8 9 10 1821 22 24 1 5 16. T he bevel 7 is secured to the hub P and is stationary. The bevels 8 and 9 are secured on the ends of `a `shaft carried in a of the arm Q. The bevel 9 drives the bevel 10 on the lower` end of the-shaft 18. The upand the'spur-wheel 15 is th us secured thereon in `a stationary manner.

' 21is a lever pivoted b y the pin 19 to the upper end ,of the shaft 18, so that its outer end4 may have yavertical movement.

16r is a pinion having a bearing 22 in the end 0f the lever 21.

2 3 is a nut, which secures the pinion 16 to the lever 21,and the wire 24, which supports and carries the moon, is secured in its top.

The end of the shaft 18 plays freely in a slot 2O in the lever 21. A washer 25 is placed between the top surface of the wheel 15 and the under surface of the lever 21, and its upper surface is inclined at an angle of ved-egrees, as `indicated by the dotted line m, which is parallel with the line c m through the centers of the earth and moon and which shows `the inclination of the moons orbit to the plane through the centers of the earth and sun, or to the earths orbit; The washer -25 may be adj usted to show the precessvion of the moons orbit. Since the washer 25 is made wedgeshaped, by turning it about the stem 18 it will raise or lower the lever 2l and hence vary the precession of the moon, Of course the washer is stationary, and as the relative positions of the earth and moon are constant a change in the position of the washer will throw the moon up or down. When the arm Q is rotated about the axis o fu, the stationary bevel 7 causes the bevels 8 9 10 to rotate and thus the shaft 18, which causes the -lever 21 to rotate about the axis/02122. Since the wheel 15 is stationary, the motion of the lever 21 causes the pin 1G to rotate and hence the moon to revolve around the earth.

The apparatus described is so arranged that the moon revolves about the earth from west toeast. Since when the moon revolves about the earth it always presents the same side to the earth, it will make one rotation on its axis, although rigidly connected to the support 2l, so that the instrument shows the rotation of both the earth and the moon. The sun is placed at S centrally over the pivot F, about which the lever L and the earth rotate. small sphere may represent the sun, or any suitable light may be located at that point.

'lhis instru ment is capable of showing the variation of the earths motion or velocity in its orbit during an annular revolution. A regular speed of the lever L and the axis fu ru about the axis o3 v3 is producedby the spring 27 and suitable regulating means, as the balancewheel/l. Since the earth makes one revolution around the` sun in one year, the shaft W rotates once in `one year, since the pinions 3 and 6 are equal, and also the pin-` i i ions 4 and 5, and causes the pin 32, attached vto the bevel 6, to Vdescribe a circle in a year. Since the lever N is pivoted to the column D independently of the lever L, these two levers are free to be moved independently about the axis@3 v3.1 When the pin 32 is in the posiend of the lever N forward, or contrary to the direction of the arrow r2, Fig. 3.

The motion of -thelever N, is the correct motion of the earthabout the sunl with reference to rapidity and regularityjthrough' space. Pin 32 plays around and is the same distance from the center of the bevel 6 (or axis v n) as the center of the earth. The earth must come nearer to and go farther from the sun. In the position shown pin' 32 is farthest from the.

sun. Then the'centerof the earth, beingover pin 32 is farthest from the s un.` A movement of ninety degrees from the position shown of bevel 6 will result in an increasing retardation of the lever N until -the lever N is behind thelever L the distance of the pin 32 from the center of the bevel G. During the following ninety degrees the lever N will be brought backward, gaining until at the point` IIO indicating January 1, when the levers N l and L are together. During the following ninety degrees the lever N is brought forward. During the final ninety degrees the lever N is retarded until it and the lever L are coincident, as at first, or in the position of July 1. The counter effect of the lever N is that of pulling backward during the time that the pin 32 is within the circle described by the center of the bevel 6 about the axis D, and from October to March, inclusive, and that of pushing backward while pin is without the circle described by the` center of bevel G about the'axis D, and from April to September, inclusive, but always serving as a retardation, and the intensity varying with the movement caused by the position, as it is over pin pin 32 moving under the impulse of the spring 27. This will allow pin 32 to move to' and fro with reference to the sun and also travel with the lever N, and the earth will be kept in true Remember, I could regulate the lever L; but the center of the earth would not always be over the center of that lever, so I apply a second lever and regulate it, and by so doing the earth will movewith the lever and receive regularity. Such action would be effective and observable, since the yearly motion would take place within a short space of time when operating the instrument tol illustrate the relative motions and positions ofv the sun, earth, and

moon.

Fig. 4 shows the base of the instrument made with a lat top surface andan elliptical margin of the same shape as the orbit of the earth. The axes coincide with the lines h2 h? and h3 h3, and the sun S is shown in the focusnear January 1.

C is the hole in the center of thev base, in which the stud'C, Fig. 2, is secured.

The sun is'shown in the focus in Fig. 4 in order to'showits relative position to 'the column C, as shown in Fig. 2.` Since the el'- lipse of the earths orbit approximates closely to a circle, the base can be madecircular, as

in Fig.' 3, and answer the purpose equally well.

The wheel 1 on the column C may be made as large asthe disk B, Fig.3, and serve both as a wheel and the parthaving the diagrams and illustrations shown in Fig. 4.

In Ithe design of a base shown in Fig. 4 the margin' is marked off into three hundred and sixty-five and one-fourth days. y XVthin the margin are two ellipses concentric with each other and with the margin, and they are divided circumferentially into spaces. Lines drawn radially inward from the margin separate the said spaces from eachother, and the radial lines niark the positions of the first day of each month,andtheinterveningspacebetween two such adjacent lines shows the intervening month. The name of the month is placed in the space between the two adjacent radial lines and the inner ellipse, and the namesof the days .are placed in the space between the margin and the adjacent ellipse andjust inside of the marginal row of day-marks. each month and the tlgure l are placed by the radial line separating months and drawn from the marginal markindicating the first day ofthe particular month. The names of other important days are also written in the marginal space at the marks denoting those days. Radial liuesare drawn from the inner ellipse inward, forming twelve central spaces, in which the names or signs of the zodiac are placed.

The arrangement shown in Fig. 4 furnishes the longest line for the divisions denoting days and convenience of referring any day of The name of any month to that month and to the whole .year and places the signs of the zodiac in a path of the earth in its orbit. Starting with January 1, the earth would pass over the margin of the chart. By following the daymarks around all of the days off-January will be passed and February 1 reached.v In that manner all days of the year may be passed over and the corresponding particular features and phases observed. Each month has its par'- ticular. number of days, and the month of February is shown with one-fourth of a day over three hundred and sixty-tive, which illustrates how in four years a complete additional day is added to the twenty-eight days of February. The days limiting the different periods of the zodiac are marked in the day marginal space, and radial lines are drawn from these marks inward, separating the contiguous spaces v whichv represent the periods during which those signs are associated with particular portions ofthe year. An index I, Fig. 4, may be attached to the under side of the end 35 of the lever L and be bentdownward over the wheel 1 and have its point pass over and near the day-marks on the margin of the base B. The index is shown in Fig. 4 pointing to the first day of July, which is the time of aphelion. Perihelion occurs January 1, and is marked on the margin of the base.

In using the instrument the spring 27 would cause the lever L and supported parts to ror tate regularly around the pivot F in the direction of the arrow v and the pointer I would indicate the relative positions of the sun and earth in space during such motion and also the time of month and year, the chart'and index being referred to in observing positions in space at certain times and the moving earth and moon being referred to in observing the motions of those bodies, since the pointer is at Julyl when the earth is in the position of January 1.

The essential features of this invention embodied in this instrument consist in a stationary central support supporting framing carrying the earth and moon and pivoted to the said support, stationary toothed wheels, and turning toothed wheels engaging the latter and mounted on proper shafts.

The drawings are made to a scale in which four inches equal one foot, and the proportions are intended to be practicable for construction and use. The mechanism must be designed with dimensions and speeds which will cause correct relative inotionsof the earth about the IOO IIO

sun and the moon about the earth. If the bevels 3 and G have the same number of teeth and the bevels 4; and 5 have the same number, then the arm Q will rotate about the axis v v in the same time that the lever L rotates about the axis o3 c3.

In order to have the earth rotate once every twenty-four hours and make three hundred and sixty-five revolutions in one year, two hundred and ninety-two teeth would be made on wheel l1, twelve on pinion 12, one hundred and fifty on wheel 13, and ten'on the bevelpinion 14. In order to have uniformity of action between the shaft W and the lever L, the

wheel l would have two hundred and ninetytwo teeth also. of the earth is nine inches, that of the moon two and one-half inches, and the distance of the center of the sun from the center of the earth is twenty inches, and that of the moon from the earth nine and one-half inches.

The following phases and eventsare shown on lthe chart in Fig. 4: January 1, earth in perihelion; February, sun slowest, time later than clock-time; March 21,` spring equinox; April 15, sun and clockcoincide; June 14, sun and clock coincide; June 21 sun twentythree and one-half degrees north of the equator; July l, sun in aphelion; September 22, autumnal equinox; November 1,sun fastest; December 21, sun twenty-three and one-half degrees south of the equator; December `.24, sun and clock coincide.
